CAR-T疗法诞生以来，安全性一直是悬在头上的达摩克利斯之剑。CRS、ICANS以及长期安全信号，是无法逃避的话题。日前，FDA的几位高管在Annals of Interal Medicine上发表的一篇文章很好地阐述了他们的立场：将以灵活的监管方法支持这些新型细胞疗法的开发。

Consider an example. An AI rewrites a TLS library. The code passes every test. But the specification requires constant-time execution: no branch may depend on secret key material, no memory access pattern may leak information. The AI’s implementation contains a subtle conditional that varies with key bits, a timing side-channel invisible to testing, invisible to code review. A formal proof of constant-time behavior catches it instantly. Without the proof, that vulnerability ships to production. Proving such low-level properties requires verification at the right level of abstraction, which is why the platform must support specialized sublanguages for reasoning about timing, memory layout, and other hardware-level concerns.
